Peter is replacing five broken sections of the picket fence around his house. The length of each section is between 7 and 9 feet, and the height of each section is between 3 and 5 feet. Peter estimates the area of the five sections that need to be replaced to be 200 square feet. Is this a reasonable estimate?
Answers
To do this, we need to have a range , with the boundaries of the range being the lowest expected area and the highest expected areas respectively.
The lowest expected area would take into recognition the lest length and height which is just 3 by 4 . The area of a section here is thus 3 * 4 = 12 sq.feet
Since there are 5 sections, the total area here is thus 12 * 5 = 60 sq.feet. This is the minimum total area of the sections
For the maximum, we compute the area of the sections using the highest length and height. This is 5 by 6. The area here would be 5 * 6 = 30 sq.feet . Since there are 5 sections, the total area here would be 30 * 5 = 150 sq.feet
Hence, we have the area falling between 60 sq.feet and 150 sq.feet
Since the estimates fall between the boundaries and in fact is closer to the maximum, it is a good estimate

What is the equation of the line that passes through the point (2,−1) and has a slope of 3/2
Answers
Answer:
y=3/2x-4
This is the answer.
Given :-
A line having a slope of 3/2 passes through (2,-1) .
To Find :-
The equation of the line .
Answer :-
According to the question ,
m = 3/2
Point = (2,-1)
We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )
Substitute ,
y - (-1) = 3/2 ( x - 2 )
y + 1 = 3/2x - 3/2*2
y +1 = 3/2x - 3
2( y +1) = 3/2x *2 - 3*2
2y + 2 = 3x - 6
3x -2y -8 = 0

A rectangular field is 90 yards long and 60 yards wide.Give the length and width of another rectangular field that has the same perimeter but a larger area.
Answers
Answer:
The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m
Step-by-step explanation:
The perimeter of the existing field is
2(l + b)
= 2(90 + 60) = 2(150) = 300 yards
So we want another field having the same perimeter but a larger area
The area we have here is 90 * 60 = 5,400 square yards
If we had 80 by 70
Perimeter will still be 2(70 + 80) = 150
But the area will be 80 * 70 = 5,600 square yards
A charity marathon in Keller is 26.2 miles. There are approximately 1.61 kilometers in 1 mile. Which measurement is closest to the numbers of kilometers in the charity marathon?
Answers
Answer:
42.182km
Step-by-step explanation:
From the question, we know :
There are approximately 1.61 kilometers in 1 mile.
A charity marathon in Keller is 26.2 miles.
The measurement that is closest to the numbers of kilometers in the charity marathon is:
1 mile = 1.61 km
26.2 mile = x km
Cross Multiply
1 mile × x km = 26.2 mile × 1.61 km
= 42.182 km
The number of kilometers in the charity marathon is 42.182km
